SPLICED CONSTRUCTION OF TWISTED PAPER YARN FOR USE IN WEAVING Filed Oct. 5, 1955 United States Patetit O SPLICED CONSTRUCTION OF TWISTED PAPER YARN FOR USE IN WEAVING Benjamin M. Kimball, Gilman, Vt., assignor to The Cellucord Corporation, New York, N. Y., a corporation Application October 5, 1955, Serial No. 538,575 7 Claims. (Cl. 15453.6)

As is well known to those versed in the art, various constructions tufted carpets and other uses above indicated. However, all of such splices have proved unsatisfactory, being of insuflicient strength to withstand the tension equipment.

Accordingly, it is a general object of the present invention to provide a splice construction, and method of making the same, which overcome the above-mentioned disother parts of a loom.

It is a further object of the present invention to provide a highly improved splice for twisted paper yarn, the advantageous characteristics mentioned in the of extremely simple construction, and which can be made quickly, easily and economically, either by hand or automatic equipment.

Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings, which form a maten'al part of this disclosure.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.

In the drawings:

Fig. 1 illustrates an early stage in the method of the present invention, wherein a pair of paper yarn sections are being tied together.

Fig. 2 shows an intermediate stage in the method and illustrates a pressure sensitive adhesive coated tape being wrapped about the tied yarn sections.

Fig. 3 illustrates the finished yarn section juncture or splice.

Fig. 4 shows a slightly modified form of splice or juncture according to the present invention.

Fig. 5 is a longitudinal sectional view showing the slightly modified splice of Fig. 4.

Referring now more particularly to the drawings, and specifically to Fig. 1 thereof, there is illustrated therein a pair of yarn sections and 11 each fabricated of paper and twisted in the conventional manner. Twisted paper Patented Oct.-1, 1957 strip from A: inch wide and up has been found satisfactory for use in weaving carpets and rugs, and backings for other woven and non-woven allied materials. The adjacent end portions 12 and 13 of the respective yarn sections 10 and 11 are first tied together in a knot 14. While the knot 14 is illustrated as being a square knot, it is appreciated that numerous other types of knots may be employed without departing from the invention. For ex ample, a weavers knot, a granny knot, and a modified weavers knot have all been found entirely satisfactory.

When the knot 14 is drawn tight, see Fig. 2, to securely attach the yarn sections 10 and 11, there necessarily remain free terminal yarn portions 15 and 16 of the yarn sections 10 and 11, respectively. While the bare or uncovered knot 14 will not loosen, open, or come out if the yarn sections 10 and 11 are used in the weaving pr cedure, the free terminal ends 15 and 16 and the knot itself frequently catch in the heddles reed or adjacent yarns or other loom parts and cause rupture of a yarn section.

It is, therefore, desirable to provide an externally smooth covering, firmly secured, surrounding the knotted adjacent end portions 12 and 13 of the yarn sections.

12 and 13. Such a strip or othersuitable-material, and its adhesive coating preferably sensitive to slight pressure. More particularly, the strip or tape 18 is arranged at an angle with respect to one yarn section 11 and has one end portion initially wrapped about and secured to the latter yarn section adjuncture or splice of the yarn sections.

The tying and wrapping procedures of Figs. 1 and 2, respectively, may obviously be accomplished by hand; and, such steps may also be performed by existing automatlc equipment, if desired. As a modification of the cent 11a to define a relatively smooth external contour, it may be desirable to roll the adhesive material into the desired external contour, as between suitable rollers or the fingers of an operator, preferably just before the material solidifies or sets.

In the modification of Figs. 4 and 5, the covering 20a also serves to reinforce the attachment of yarn sections 10 and 11a by the knot 14a, and operates by its externally streamlined contour to insure free yarn movement through a loom or other device. That is, the covering 20a prevents the knot 14a or its free terminal ends from catchingon the heddles or reed or adjacent yarns or, other parts of a loom, as described hereinabove in connection with the cover 20 of Fig. 3. From the foregoing, it is seen that the present invention provides a slideor juncture for twisted paper yarn, and method of making the same, which fully accomplish their intended objects, and are well adapted to meet practical conditions of manufacture and use.

Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications maybe made within the spirit of the invention and scope of the appended claims. I

Having thus described my invention, what I claim as new and desire to secure by Letters'Patent, is:

1 An elongate twisted paper yarn comprising at least two endwise adjacent sections having their adjacent end portions securely tied together in a-knot,.and a covering closely surrounding and adhesively secured to the knotted and adjacent end portions of said sections, said covering tapering in opposite directions longitudinally of said sections to define a relatively smooth external. contour for unhampered yarn movement through a loom. I

2. A yarn according to claim 1, said covering comprising a pressure sensitive adhesive coated tape spirally wound about the knotted and adjacent end portions of said sections. a

3. A yarn according to claim 1, said covering comprising a coating of adhesive material on the knotted and adjacent end portions of said sections.

4. A yarn according to claim 1, said covering comprising a coating of flexible plastic material adhesively secured on the knotted and adjacent end portions of said sections.

5. An elongate twisted paper yarn for use in weaving, said yarn comprising at least two endwise adjacent sections having their adjacent end portions securely tied together in a knot, and a pressure sensitive adhesive coated tape spirally wound about the knotted adjacent end portions of said sections to reinforce their attachment by said knot and define a relatively smooth covering for said adjacent end portion. 7

6. An elongate twisted paper yarn'for use in weaving, said yarn comprising at least two endwise adjacent sections having their adjacent and portions securely tied together in a knot, and a sheath of flexible material enclosing the knotted adjacent end portions of said sections to define a relatively smooth covering on the knotted adjacent end portions of said sections and having a smooth configuration tapering in opposite directions longitudinally of said sections.

7. An elongated twisted paper yarn for use in weaving, said yarn comprising at least two endwise adjacent sections having their adjacent end portions securely tied together in a knot, and a coating of flexible plastic material adhesively secured on the knotted adjacent end portions of said sections to define a relatively smooth covering for the knotted adjacent end portions of said sections.
